In the drawings:

The dotted lines in Figs. 1 and 2 'illustrate the major portion of a usual hay baling vehicle which is indicated as a whole by the reference numeral I. The baler I includes an elongated hollow body 2, extending lengthwise with relation to the direction of travel of the same, and the major portion of which is rectangular or substantially square in cross-section. The front or forward end of the body is the end which supports a unit for powering the baling mechanism and is not shown in the drawings, the forward portion of the body having been broken off at the jagged lines 3, The front end of the body also includes adraft coupling means -whereby the vehicle may be attached to a tractor for propulsion.

The words left handf and right hand used herein refer to the respective sides as they would appear to a person standing at the rear of the vehicle and facing forward, or toward the vehicles direction of travel.

The vehicle is mounted for movement along the earths surface upon |a left handiwheel 4, carried rigidly upon a shaft 5 which projects through the body I `beyond its right hand side to receive anotherand similar wheel, not shown.

`A tatably mountedat thefright hand side of the body 2 for rollable engagement with the earths surface. The drum 6 is equipped with projecting spikes and other mechanism not shown, whereby it gathers mowrllv hay from the eld, and raises and ldischarges it upon the floor 'I of a feeder bin 8, Y The feeder bin, has a vertical right hand end -wall 9 and a rearv wall or back sheet Ill. The left hand vend ofthe floor 'I extends leftwardly tothe right handopen end of a feeder drum housing I I. A rotatably mounted power driven feeder drum, not shown, occupies the housing II and acts to feed hay from the floor 'I into an opening in the right hand side of the body 2 at the rear of the axle 5.` The hay is fed into the body 2 'at a point substantially midway between the forward end 3 and the rearmost end I2 thereof. Just forwardly of the housing II, the body 2 has an enlarged portion with a rounded top I4, and this enlarged portion contains a mechanical rain, not shown, which forcibly urges the hay toward the rearof the body. The portion of the body 2 in which the hay is compressed, or that portion lying to the rear of the housing II, is termed a bale case, and the bale case, which is pick-upV cylinder or gathering drum 6 is roindicated by the reference numeral I5, has both its left and right hand sides open. The rear end of the bale case is open to permit ejection of the completed bales upon the ground, or if desired, upon a trailer.

The vehicle is further supported upon a second pair of -wheels which lie to the rear of the wheel shaft 5. The left hand one of these wheels is indicated by the reference numeral I6, `and is shown as being mounted upon a shaft I1 which passes substantially beneath the body 2, the housing II and the feeder floor 1, Where it receives at its extreme right hand end, the other wheel of the pair. This other wheel which is like the wheel I6, is located below and to the right hand of the end wall 9 of the feeder 8.

The bale clase I5 is formed by four horizontal rearwardly extending angle iron members, each of which extends along one of the corners of the case. The upper left hand one of these corner members is indicated Iby the reference numeral I8, and the lower left hand one is indicated by I9 (Fig. 8). The top and bottom of the bale case are solid, while the two sides are open except for the vertical flanges of the four corner members.

As the hay enters the body 2 through the side opening under the drum housing II, and as the mechanical ram under the rounded top I4 of -the body compresses the hay, the hay is forced rearwardly into the bale case I5. As more hay is picked up by the gathering drum 6 and is placed by the feeder drum in the path of the ram, the previously compressed hay is forced to travel rearwardly of the vehicle and along the bale case.

This, of course, takes place during the time the vehicle is being drawn along the earths surface. The bales are permanently formed during their travel rearwardly through the bale case by tying two strands of wire around each bale lengthwise. If some means were not provided for dividing the-body of compressed hay into sections or divisions to form' the bales, the compressed hay would be ejected from the rear end I2 of the bale case I5 in continuous stream. In order to divide the body of compressed hay so that it may be tied into bales, a divider is thrust into the left hand side of the compressed hay body.

` The dividers are conventional, and each consists of two heavy metal parallel prongs or pointed needles 20 land 2I, which are rigidly attached together in spaced relation by a cross bar 22. The divider is mechanically forced into the compressed hay body from theleft hand side thereof so that its two points are located substantially eveny with the right hand surface of the hay body. The front and rear edges of the needle are provided with longitudinally extending superficial grooves 23 so that the bale wires may be thrust manually along the channels through the hay body.,

As mentioned abovey the dividers are mechanically thrust through the compressed hay body and this is accomplished by mechanically moving abale divider box or carriage which supports the divider in proper position for its points to enter the hay body.

The divider thrusting mechanism includes a horizontal track member 25 which projects laterally from the left hand side of the body 2, and is rigidly carried thereby. It also includes aV box or carriage 26 which travels along track member 25 on rollers 21 (Fig. 8). A handle 28 is provided on the box 25 so that the box may be manually rpulled to the outer end of the track J i'. tor .ine.ehepieaiir .forcibly ineviiig the ditider bei; iii trom the feeels d.1goitionof Figd. to the right. hand and .toiterd the pale .order to plunge the divider .tiirpiigii the hay body, I provide a heavy rrietai breeliet tl?. rriiith is. welded to .the left. lifted .of .the Ahet; dit. rig'dir eerried .by the left hand end .oi .a siidable doii- The .rod :3Q er: terids. beneath theyehiele .body z .to tiiexright. haiid. iride thereof, .and its other or right .hand ehdis s dable with bearingtl car;

7 other end of which is bifurcated to straddle the arm 4| of the divider carriage actuating mechanism above described herein (Fig. 3). A pivot pin 11 acts to pivotally connect the pitman 'I6 to the arm 4|.

It is obvious that constant rotation of the driven member 62 will cause the arm 4| to be successively swung forwardly and rearwardly with its upper horizontal portion acting as an axis. Since only the rearward movement of the arm 4| acts, through the cable 39, to cock the divider carriage, it is not desirable to have the driven member in continuous rotation, but instead, it is desirable that the arm 4| be swung rearwardly only when the divider carriage is to be cocked To this end, rotation of the driven member 62 of the clutch is limited to but one complete revolution at a time. Since the driving member 60 is in constant rotation, and since the driven member 62 is rotated only when the latch is engaging both members, movement of the latch out of the engaged notch 6l will release the driven member 62 so that member 62 may return to its original radial position.

A retrieving spring 18 (Figs. 1, 2 and 7) attached to the slip-collar 36 acts to draw the collar 36 and the cable 39 toward the right hand end of the rod 39, and the lever 4|, pitman '16, crank-arm T3 and driven member 62 are thereby returned to their original positions as shown in Fig. 3. Figure 5 shows the clutch member 62 and crank-arm 13 as they appear after a partial revolution has been made, and Fig. 4 shows them as the revolution is just being completed.

In order to withdraw the latch 18 from its engaged notch 6| in the driving member 69, when the crank-arm 13 has substantially completed one revolution, the trip mechanism 80 of Figs. 4 and 5 is provided.

This trip mechanism 80 consists substantially of a plate 8| welded 0r otherwise rigidly attached to the right hand surface of the body 2 adjacent the clutch mechanism 50. The plate 8| has a rigidly supported horizontal pivot pin 82 which projects outwardly from the plate 8| in a right hand direction. Upon the pivot pin 82 is rotatably mounted a tubular sleeve 83 having a perpendicular arm 84 at one end, and a similarly projecting trip-plate 85 adjacent its other end. The trip-plate 85 has an arcuate or bevelled edgesurf ace 86 which lies close to the peripheries of the two clutch members 60 and 62 at their abutting edges, and in the path of the latch 10. The surface 86 is so located that when the protruding end of the latch 'l0 engages it, the latch is moved laterally out of the engaged notch 6|. Fig. 4 shows the latch as it is being disengaged by the arcuate surface 86.

Since the sleeve portion 83 of the trip mechanism 80 is pivotally mounted on the pivot pin 82, the trip-plate 85 may be swung forwardly out of the path of the latch l0.

The arm 84 of the trip mechanism 80 is pivotally connected to one end of a link 81 which extends along the right hand side of the body 2 and is pivotally connected at its rear end to the projecting arm 86 of a bell-crank which has a horizontal central portion 89 extending beneath the body 2 to the left hand side thereof. The left hand end of the central portion 89 of the bellcrank has a perpendicular arm 90, the outer end of which is attached to a helical spring 9| which urges the arm 90 toward the front end of the body 2. The spring 9| therefore acts to normally hold the trip plate 85 of the trip-mechanism 80 in the path of the latch 10 as shown in Fig. 4. The result is that the driving member 66 of the clutch mechanism may normally rotate continuously without driving the driven member 62 to rotation. It is obvious, however, that should the trip plate be moved away from the latch 10, then the spring 'l2 of the clutch mechanism will urge the latch 7U toward the driving member 60 and into one of the notches 6| therein. When this transpires, the arm 4| will be moved forwardly and the cable 39 will cock the divider carriage, as above described.

' As soon as the latch I0 is disengaged from the trip-plate 85 and engages in one of the notches 6| of the driving member 60, the spring 9| acts to return the trip-plate to its normal position, so that when the latch has made one complete revolution, it will again be disengaged from the driving member 60. It is therefore evident that rearward movement of the trip-plate 85, and release of the latch 10 to the action of the spring 12 is the means by which cooking or re-setting of the divider carriage is controlled. The mechanism by which the trip-plate is moved away from the latch 19 will be more fully described hereinbelow.

It is pointed out that the operation of the divider carriage cooking or re-setting mechanism thus far described, is substantially as follows:

With the clutch parts in the positions shown in Fig. 4, the trip-plate 85 holds the latch 10 out of the path of the notches 6| in the driving member 60. The spring 33 on the rod 30 is compressed, and the slip collar 36 is at the left hand end of its travel on the rod 30, with the retrieving spring 18 in stretched condition. Should the rod 30 and bracket 29 have been previously released to the action of the spring 33, and should the trip-plate 85 of the trip mechanism 80 now be simultaneously moved out of engagement with the latch 10, the spring 12 will urge the latch 1U into engagement in one of the notches 6| in the driving member 69, and the driven member 62 will begin a revolution with the driving member. As the driven member makes this revolution, the arm 4I will be moved by the pitman 16 toward the rear of the vehicle which will slacken the cable 39. During this rearward movement of the arm 4| the spring 18 takes up the slack in the cable by moving the slip-collar 36 to the right hand end of its travel on the rod 30.

Immediately upon actuation of the trip-plate 85, as above described, and as soon as the protruding end of the latch 'I0 has passed the tripplate, the trip-plate is returned to its original position, as shown in Fig. 4, by action of the spring 9| upon the bell-crank (88-89-90). During the revolution of the driven member 62, the pitman I6 moves the arm 4| toward the rear of the body 2, and this movement pulls upon the cable 39 and causes the slip-collar 36 to contact the set-collar 31 on the rod 30 and move the rod 30 to the left hand end of its travel, thus cocking the divider carriage in position to repeat the operation. When the latch I0 makes one complete revolution with the driven member 62, it will again contact the arcuate surface 86 of the trip-plate 85, and be withdrawn from the notch 6| in the driving member 60.

In considering the above described cycle of operation it must be taken for granted that some suitable means is provided for latching the divider carriage in its cocked position, and that prior to the start of the cycle, such latching means was released.

The latching of the divider carriage in cocked A jariclitsirelease toftlde actions-of the spring is 'accompli'shed by theherei'nabovedescribed 3'4Fwl1i'chf iss lidably carried" along4 the -left'lliarrdside or theb rlek boxA The forward end or therlatch-link 3ll`i`s pivotally f connected to thellatfeh' not-shown, which holds the divider carriage in cockedi pdsitin. Forward movement of the latch link v Facts torel'easert'he divider carriage 20'.. Meansfor moving the ,latch-,link 33 longitudinally will be more fully describedl hereinbelow. v ,j I,

The foregoing description 'explains the construction and operation offthlef apparatus by which the? balerdivider is thrust'` into ythe compressed ibridi? of. hay in the bale. box; with the exception of" the divider carriage releasing"meansganct'also explains the mechanism for cooking the divider carriage. The description has not included the mechanism used to withdraw the bale divider from the compressed hay after the bale has been tied, and as the bale reaches the rear end portion of the bale box. This latter operation is accomplished by the above described clutch actuation of the arm 4| in the following described manner.

To the lower end of the arm 4I, and beside the cable 39, is also attached a second cable I 03 which extends rearwardly along the right hand side of the body 2 through a pulley stirrup I0| attached thereto, extends beneath thebale-box I5 toward the left hand side thereof, where it attaches to the right hand end of a crank-arm |02 (Figs. 1, 2 and 8). The crank arm |02 extends horizontally beneath the bale-box I5 and at the left hand side of the bale-box, the crank arm has a vertical portion |03 which is journalled in suitzlibe upper and lower bearing brackets |04 and Intermediate the ends of the vertical portion |03 of the crank arm |02 are provided two identical rigidly mounted ejector arms |06 which are l plate-like in form, and which lie with their edges normally presented horizontally along the left hand surface of the compressed body of hay. The ejector-arms have their free forward end portions reduced in width to form points I 01 so that as the divider moves with the compressed hay body rearwardly of the bale-box I5, the points will engage between the haybody and the cross-bar 22 of the divider.

The upper end of the vertical portion |03 of the crank-arm |02 is equipped with a rigidly mounted horizontal arm |08 to the outer end of which is connected a spring |09 for urging the arm |08 and the crank-arm |02 toward the rear of the bale-box. The spring |09 thus holds the ejector-arms |06 in close proximity to the hay body.

The relative arrangement of the crank-arm |02, the ejector-arms |06, the cable |00, and the arm 4| is such that when the arm 4| is moved forwardly by the clutch mechanism, the ejectorarms |06 are swung outwardly from their normal positions adjacent the hay body, and such outward movement of the ejector arms |06 will act to withdraw the bale divider from the hay body, provided the divider is in such a position that its cross-bar 22 is engaged over the points |01 of the ejector arms.

In order to insure actuation of the arm 4| only when the bale divider is engaged over the points of the ejector-arms |06, the rear end of a link 35 is pivotally connected to one end of a trip-lever ||0 which is pivotally mounted on the lower left hand frame member I9 of the bale box I5. The forward end of the link 35 is pivotally connected leverI Uris `so located' 'that it lies in thef'path 'of 'the traveling bale divider, 'and las, thev divider travels rearwardly inr` the baley box,` along with the body of compressed hax'ethe divider contacts the" trip-lever andf'orces it rearwardly.

describing tlie1 operation of the clutch .50 and'Y associated? mechanisms; namely; the di- Viierfcarriage cooking4 mechanismwand the di'- vider withdrawing mechanism, it was pre-supposed that the divider carriage had previously been released to the thrusting force of the spring 33, and that the divider carriage had first been sprung and kthe forward divider had been thrust into the hay body. It was also stated above that longitudinal movement of the latchlink 34 was the means by which the divider carf riage is released or sprung The latch link 34 is moved forwardly to release the divider carriage to the thrusting action of the spring 33, by contact during its rearward travel of the rearmost divider with a lever |20 pivoted to the bale-box |5, and also to the rear end of the latch link 34. The dotted line position of the rearmost bale divider of Fig. 1 shows the divider as it contacts the lever |20 to actuate the latch-link 34 toward forward movement.

It is pointed out that this contact takes place a few inches ahead of the contact of the rear divider with the trip-lever ||0 which starts the operation of the clutch through one of its cycles. thrust into the hay body a little prior to the time that the divider carriage is again cocked and the time at which the rearmost divider is withdrawn from the hay body. In other words, the rear bale divider is withdrawn from the hay body after the actuation of the divider carriage to thrust the other bale divider into the compressed hay body. After that portion of the operative cycle has taken place, the divider carriage is automatically reset or cocked for the next operation, and the ejector-arms |06 are simultaneously moved back to their normal positions to again engage the next rearwardly traveling bale divider.

It is thought to be apparent that some changes could well be made in the preferred embodiment of the invention which has been shown in the drawings and described hereinabove, and I therefore do not wish to be confined to the specic structure disclosed hereinabove, further than I am limited by the scope of the appended claims.

It is pointed out that linkage adjustmentsmay be made in the apparatus so that bales of diierent length can be provided for. Since such adjustable features would fall within the exercise of only mechanical skill, it has not been thought necessary `to show them in detail and describe them hereinabove. I

I claim:

l. In hay baling apparatus, the combination with mechanism for driving a'divider into a body of compressed hay, of; power driven means for re-setting the mechanism; and power driven means for withdrawing the divider from the hay body.

2. In hay baling apparatus, the combination with mechanism for driving a divider into a body Consequently, the forward divider is 1 1 of compressed hay, of power driven means for re-setting the mechanism; and power driven means for withdrawing the divider from the hay body, both of said means being operable in timed relation to each other.

3. In hay bvaling apparatus, the combination with mechanism for driving a divider into a moving body of lcompressed hay, of; power driven means for re-setting the mechanism; and power driven means for withdrawing the divider from the hay body, both of said means being operable in timed relation to the movement of the hay body.

4. In hay baling apparatus, the combination with mechanism for driving a divider into a moving body of compressed hay, of; power driven 12 means for re-setting the mechanism; and power driven means for withdrawing the divider from the hay body, both of said means being operable in timed relation to each other, and in timed relation to the movement of the hay body.
